Can I get diameter of droplets in POSDAT.F?
 

Hello,

I'm faced with an obstacle. Can I get diameter of injected droplets from a nozzle in POSDAT.F? There is no variables, which is realated with droplet, in POSDAT.F as I know. Isn't there anybody who had an experience to get it?

Thanks

Introduce common block "COMMON /C33003/ DRD(4)" and inquire the diameter in parcel IDR with DRD(IDR).

Hello,

Thank you, Thomas. But it's still difficult to understand. Why 4 in DRD(4)? I just got "DRD(IDR)=0" in "DO roof" (IDR=1,10 and DRD(IDR)) although initial injected droplet dia. is 0.00015 (M) in average. In POSDAT.F, can we endow a dimension with DRD like DRD(*)? I wonder where is the information of DRD in POSDAT.F from? Don't we need any other subroutines to get it except POSDAT.F? Thank you for sharing of your time.

Best regard, SJLee

DRD is one of many STAR parameters that can be inquired by the user. The name of the common block and the parameter's format are defined by STAR. Thus, there is no need to create this parameter yourself. Check the user's guide or ask your local support for information material concerning user subroutines and common blocks.
